https://en.wikipedia.org/wiki/Congress_of_Vienna
The objective of the Congress was to provide a long-term peace plan for Europe by settling critical issues arising from the French Revolutionary Wars and the Napoleonic Wars. The goal was not simply to restore old boundaries but to resize the main powers so they could balance each other and remain at peace. For the Caribbean however the congress could not form consensus and nothing was said in the final act. It turned the Caribbean into a continuous area of turmoil and war.
